Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a quantitative dispensing container from which liquid, powder, granular material, etc. can be easily dispensed in fixed amounts.

<Prior Art> As a conventional metering dispensing container of this type, a technique as shown in, for example, Japanese Utility Model Publication No. 57-3969 is known.

This technology uses the container body, inner stopper, and
It is constructed using a coil spring, a spring holder, an outer cap, etc., and when dispensing the contents, the outer cap is completely screwed onto the container body, and the holding protrusion of the outer cap is pushed into the locking part of the spring holder. A gap is formed between the stopper and the spring holder, and the container body is turned upside down to allow the contents to flow out from the gap and stored in the inner stopper.Then, the container body is turned upright, the outer cap is removed, and the contents are stored in the inner stopper. This allows a certain amount of the contents stored in the stopper to flow out.

<Problem to be solved by the invention> However, the conventional quantitative dispensing container described above has an extremely large number of component parts and a complicated structure, making it difficult to assemble and operate, and is therefore prone to failure. There were problems such as the possibility of this occurring and the cost being high.

The present invention relates to a completely new technique developed in view of the above-mentioned conventional problems.

<Means for Solving the Problems> The present invention consists of a bottle having a bottom plate having a cylindrical neck and a protruding recess at the center of the inner bottom surface and having a large hinge effect fitted to the bottom; A shaft rod is provided protruding from the neck, and several grooves are bored along the entire length of the outer circumferential wall, which has a height slightly longer than the vertical height of the neck, and an outer diameter approximately equal to the outer diameter of the neck at the upper end. The metering tube is fitted into the neck so as to be able to rise and fall freely, and the lower end of the shaft protruding from the lower end of the metering tube is inserted into the protruding recess of the bottom plate of the bottle. This is a fixed-quantity dispensing container characterized by being constructed by fitting together.

<Function> As mentioned above, the present invention combines a bottle with a bottom plate with a large hinge effect and a metering cylinder with a cut groove on the outer circumferential wall and a shaft on the lower bottom surface. By moving it, the metering cylinder fitted to the neck of the bottle can be raised and lowered,
Thereby, it is possible to fill the metering tube with liquid or the like through the cut groove of the metering tube, or to pour it out to the outside.

<Example> An example of the present invention will be explained in detail with reference to the drawings. In Fig. 1, 1 is a bottle, and the upper end thereof is provided with a cylindrical neck 2 like a general bottle. is,
A screw 3 is provided on the outer periphery of the neck 2, and a bottom plate 4 made of an elastic material having a substantially hemispherical shape and having a large hinge effect that can be bent back and forth is attached to the bottom of the bottle 1. A projecting recess 5 is integrally provided at the center of the upper surface of the shaft 4, into which a lower end of a shaft rod (to be described later) can be fitted.

Next, reference numeral 6 denotes a metering tube that can be fitted into the interior of the neck portion 2 so as to be able to rise and fall freely, and has a length slightly higher than the height (vertical length) of the neck portion 2, and this metering tube 6
Several grooves 7 are bored in the outer circumferential wall of the metering cylinder 6 over almost the entire length thereof, and the liquid, powder, or granules can enter and exit the metering cylinder 6 through the grooves 7. has been done. Reference numeral 8 denotes a shaft rod integrally projecting from the center of the lower bottom surface of the metering cylinder 6, and its lower end is fitted into the protruding recess 5 of the bottom plate 4. Further, at the upper end of the metering tube 6, there is a cap having a diameter larger than the outer diameter of the metering tube 6 and approximately equal to the outer diameter of the neck 2, which can seal the opening of the neck section 2 and prevent the metering tube 6 from falling deeply into the neck section 2. 9 is provided protrudingly. In the figure, 10 is a lid that can cover the neck 2.

Since the container according to the present invention has the above-mentioned structure,
In use, as shown in FIG. 2, first press the cap 9 to push down the metering tube 6 and the bottom plate 4 connected to it via the shaft rod 8, and the bottom plate 4 will be placed on the outside of the bottle 1. The metering cylinder 6 is elastically deformed so as to protrude.
The lower part of the bottle 1 extends below the lower end of the neck 2 and is exposed inside the bottle 1, and the liquid or other product (filling material) inside the bottle 1 is exposed through the cut groove 7.
G is filled into the metering cylinder 6.

Next, when the pressing of the cap 9 is stopped, as shown in FIG. the metering cylinder 6.
exposes the upper part of the neck part 2 from the upper edge of the neck part 2, thereby causing the product G to flow out from the cut groove 7 of the metering cylinder 6,
The metered product G stored in the metered tube 6 can be taken out.

<Effects of the invention> As described above, the container according to the present invention stores a metering tube with a cut groove on the outer peripheral wall in the neck of the bottle so as to be able to rise and fall freely, and connects the metering tube to a bottom plate with a strong repulsive force via a shaft rod. Therefore, by repeatedly pressing the metering tube, it is possible to fill the metering tube with a certain amount of product and then take it out in a stable state.The operation is extremely simple, and the elastic deformation of the bottom plate itself is prevented. Unlike when using a coil spring, the number of parts does not increase, and there is no risk of liquid or other filler leaking from the part where the coil spring is passed.Therefore, there are fewer failures and it is inexpensive. It has characteristics such as being able to be mass-produced.
